GAS-ROTOR DRIVE Russian patent published in 2011 - IPC F01C1/14 F01C21/06 F01C21/08 F02B55/16 

FIELD: machine building.

SUBSTANCE: gas-rotor drive consists of case in bores of which there are positioned three rotors. Relative to cylinder walls of the case two rotors form interconnected circular channels. The drive also has channels of supply and a channel of working substance withdrawal made in form of branches. Each rotor is equipped with a recess and a profiles blade responsive to a recess of another rotor. At least one of rotors has heat exchanging internal channels and a slot and is set on a stationary hollow cylinder collector. The collector has a slot in its wall conjugating with the slot of the rotor when the latter rotates. Heat exchanging channels are connected with one of the channels of working substance supply and with the internal cavity of the cylinder collector. The third rotor has a recess and controls supply of working substance to the circular channels.

EFFECT: increased efficiency of operation and simplified design of drive.
